Why do German cars are money pits and Japanese aren't? is it the management? flawed engineering? any money-pit Japanese brands? will the german car brands ever win the battle of reliability?

a LOT has to do with marketing. In Europe, germans sell more dependable models, while they sell non german made models to the US. Japanese don't do such nonsense

Oh ok, There must be some crappy japanese car brands. I heard Nissan is one of those horrible Japanese car brands.
